PS_ ON# PS_ON# is an activelow, TTLcompatible signal that allows a motherboard to remotely control the power supply in conjunction with features such as soft on/off, Wake on LAN+, or wakeonmodem.when PS_ON# is pulled to TTL low, the power supply should turn on the five main DC output rails: DC,,+.VDC,and VDC. When PS_ON# is pulled to TTL high or opencircuited, the DC output rails should not deliver current and should be held at zero potential with respect to ground. PS_ON# has no effect on the +5VSB output, which is always enabled whenever the AC power is present. Table lists PS_ON# signal characteristics. The power supply shall provide an internal pullup to TTL high. The power supply shall also provide debounce circuitry on PS_ON# to prevent it from oscillating on/off at startup when activated by a mechanical switch. The DC output enable circuitry must be SELVcompliant.
